Answer 18

lol... so... but one question @Niguyver

Answer 19

ok so it is x^2+16x right

Answer 20

so u cant factor out an x

Answer 21

are you looking for the roots?

Answer 22

i was going to factor it out like this
\[(x+a)(x+a)\]

Answer 23

Yes, but what number do we put as A?

Answer 24

so i would say 4 and then the other would be 4x

Answer 25

if you subtract you get a -16

Answer 26

\[(x+4)(x+4x)\]

Answer 27

and if you solve for x you would get a 0

Answer 28

then set them both to 0 right @Niguyver

so i would say set them both to 0 so x+4=0
and x+4x=0
then solve
